illustrated, comprises generally a disk `support or upper casing 2having a pair of laterally spaced bearings '26 formed integral therewithand located entirely therewithin; apair of parallel `horizontal mainshafts 24 rotatably supported inthe bearings 26 Within the casing 2; aperipherally notched disk 'l 3, `formed integral with the forwardend ofeach of the shafts 24 and having peripheral `engagement with openingsinthe front of the casing 2; three float-ing pins 5 associated with theperipheral notches 4 of the disks 3; abase 2l `forming afsupport for thecasing V2 and for a working table 22 disposed in front of the machine; aprimel mover illustrated as an electric motor 17 adjustably as-.sociated directly'vvith the base 2l; and a .tram of gearing connecting.the) motor 17 with the rear portions ofthe shafts 24.

The uppcrfcasing' 2 besides providingr bearings 'for the shafts 24 andfor the disksj 8, has adjoining rear openings of sufficient size topermit withdrawal therethrouglio't' the spur gears l() which are securedto the shafts @indirectly adjacent to the bearings 26. A rear cover 23encloses the rear portion of the casing 2 and provides end 'bearings forthe shafts 24, this cover also providing bearings for other transmissiongearing. The'pins 5 have tapered ends 27 which frictionally engagesocketsV in the pin supports 25, and the pins may be removed from `thesupports by means of a driftpin insertible in the holes 28. The'supports 25 have reducedend portions rotatably fitting the bores ofrollers 9 as shown in Fig. 5.

The reduced end portionsof the supports may be .provided with lubricantretaining helical grooves 29 andthe rollers E)v are V1, the tumbler Gbeing formed to automatically transfer' the successive advancingpins 5from the notches et vofone disk3 to the cooierating notches oftheother.V The tumb er 6 is supported upon apivot 34 and is oscillatableabout. this pivot, the degree of movement of the tumbler 6 being limitedby va stop pin '7 which is engageable with lower abutments formed on thetumbler'` 6.

` A helical. spring 33 engages the' surface of `in the vrecess betweenv22. cent to the .end of, the Vcorresponding pinv lthe ytumbler Gandsurrounds the pivot 31- tliereof, this spring serving to frictionallyretainthe tumbler 6` in any vpredetern'iined position until the same ispositively shifted by anadvancing roller 9. 4The medial' enlargedportion of each roller may also' be provided vvithAV an annular recesshaving eliamfered side portions 32 and having a rubber or other elasticband 31 located Withthe chanifered portions 32 thereof. Y i

The rpins 5 project away from the disks v3 and are overhung with respectto these disks, extending horizontally over the table Embracing each pinsupport 25 adja- 5, is a circular guard plate Shaving a frustoconicalouter surface. These plates extend .laterally away'from thejreai ends ofthe pin 5 and ay considerabledistance over the adjacent faces yof disks3 and of the front face of the upper casing2. As shown, the plates 3Aare freely rotatable rupon thev supports `25 and maybe freely-removed.

' The spur gearsl() secured to the shafts 211 are in mesh. with eachother and one of these spur gearsV 10 meshes directly with a pinion 11secured to a counter shaft to which 'a transmission gear 12 1s alsosecured. By

virtue of this arrangeinent, the gears 10 and hence the disks 3 arerotatable in opposite directions. The transmissiongear 12 meshes withdriving pinion 13 rWhichis secured to a countershaft the rear end ofwhich projects beyond the cover 23 and is drivingly connected tol agrooved siieave 14. The sheave 1li is drivingly connected to va slieave16 by means of a plurality of independent Vfbelts or bands 15 which areformed of flexible or resilient material such as reen forced rubber. Thedriving sheaveI 16 is secured directly tothe shaft of the driving` motor117 Whicliis supported Wi thin the base 21 upon' an adjustable baseplate 18. The

base plate 18 is guided upon the side walls of the base 21 and hasopenings therein which are penetrated by vertical threaded rod'sl)Secured at their V upper ends to lugs formed integral With the base 21.Nuts 210 co-act with the lowerthreading port-ionsV of the rods 19 andpermit vertical adjustment of the motor base 18 and ofthe motor 17`tojvary the tension on the driving` bands 15.

During normal yoperation of Vthe cantly pulling machine, the motor 17 istransmitting continuousY opposite rotary motion to the disks 3throughthe slieave 16, `bands 15, slicave let, pinion 13, geai'12,pinion 1.1 and gears 10. As the disks 3 revolve, the pins 'L3-associatedwith the peripheral notches. l,

are caused to travel about tlie'axes of rotation of the disks 3. Vhenthe pins 5 approach the tumbler 6, they are automatically transferredfrom the notch t of one disk 3 to the cooperating not-ch 4 ofA the otherdisk as indicated in Fig. 1. The transferred pin is then urged about theaxes ofthe right hand disk 3 to'ivhicli lvhas been transferred andeventually strikes the laterally projecting lower arm of the tumbler'. 6which is locatedin its pathof movement-,- and throws the tumbler G toits extreme opposite position Where Vit is held by the spring 33.V Thetumbler (5 is then in a positionto transfer the next approaching pin 5from the right hand disk to the otherldiskL In this manner thesuccessive lpinsf 5' are transferred from one disk to the vother and arecarried about the.l disk axes in/a, figure 8. course.

The candystockrwhich is to Ybe treated is placed upon:v the projectingmoving pins above the table 22, and is pulled and Worked in such amanner thatair Will' be effectively .embedded in the stock 'and willproduce a desired` change in the `color and condi-tion thereof. Afterthe candy stock Yhas been properly conditioned, the machine may bestopped and the stock removed from the pins thus placing the machine incondition for the reception of a fresh batch of stock.

During suchoperation of the machine the guard `plates 8 effectivelyprevent candy stock from enteringt-he notches t and the bearing surfacesbetweentlie disks 3 and the casing 2. The pins 5 maybe Withdrawn fromthe supports 25 for the purpose of cleaning `Vthe saine or otherwise,by; insertion of adrift pin'in the holes 28. The supports A 25V may beremoved upon removal of the rear cover 23 and of the retaining caps 30,

and theV entire machine maybe lreadily disj assembled by removal of thecover 23 and ly retains the tumbler 6 in adjusted position` Without`unclesirably retarding switching thereof by the advancing rollers 9.The use of the flexible band drive also tends to eliminate noise,besides providing an extremely elicient mechanism for transmittingmotion from the motor 17 to the propelling disks 3.

By arranging the motor 17 within the base 21, this motor is effectivelyprotected against damages. The Weight of the motor 17 and of the base 18is utilized tok produce the proper tension of the driving bands 15. Ifgreater tension is desired the lnuts 2O cooperating with the rods 19 maybe lowered, Whereas, the tension may be reduced by raising the nuts 20in an obvious manner. Therear cover 23 besides permitting convenientassembling and dismantling of the machine, permits effective lubricationof all of the bearings without danger of havingV the lubricant escape,andcome inl Contact with the stock being treated. The grooves 29 on thesupports 25 may be'lilled with grease thus permitting-freerotation ofthe pins 5 with respect to the rollers 9.V

It should be understood that it is not de.-

sired to limit theinvention to the exact de-v tails of construction andoperation `herein shown and described, for various modifica.- tionswithinthe scope of the claims may o'ccur to persons skilled in the art.
